this way.

From F. 10 it appears that where the stable manure was buried 
eight inches below the surface, the yield was perceptibly larger than 
where spread upon the surface ; the difference being at the rate of 
about 248 pounds of cured leaf per acre. 
The differences between F. 12 and F. 13 and between F. 14 and 
F’, 15 are so slight as to be inconsiderable. 
Where no fertilizer was applied the yield was smallest of all, while 
the per cent of cured leaf was highest. 
The conclusions suggested, if any, are that the amounts of super- 
. phosphate and chloride of potash used produced an effect upon the 
yield equal to the given amount of stable manure applied on the 
surface. 
Burning Quality. 
We submitted samples of the tobacco grown under the various 
conditions to Mr. John Brand, of Elmira, N. Y., a tobacco packer 
of long experience. He pronounced the samples grown upon soil 
fertilized with stable manure to burn decidedly freer than those from 
the soils differently treated. All, however, burned with a white ash. 
Mr. Brand is of the opinion that in a soil containing abundance of 
lime, tobacco always burns with a white ash; and that in such soils 
the use of commercial fertilizers will not affect the color of the ash. 
Varieties. 
We have continued the growing of the different varieties of 
tobacco grown upon the station in 1882, with the view of noting the 
effect of continuous growing on our. soil, upon the quality of the 
leaf. With a single exception, we have noticed little change in the 
character of the leaf. A variety, of which the seed was obtained 
from Messrs. Thorburn & Oo. in 1882, under the name Hungarian, 
produced that season a remarkably thick leaf, absolutely worthless 
for cigar purposes. In 1883 the leaf was thinner, and in 1884 it 
was so fine in texture that it was pronounced equal in quality to that 
of any variety tested. This change in character is doubtless due to
